Spinal arteriovenous malformation (AVM) A spinal arteriovenous malformation (AVM) is an abnormal tangle of blood vessels on, in or near the spinal cord. This disruption in blood flow deprives the surrounding cells of vital oxygen and causes cells in your spinal tissues to deteriorate or die.
It is not impossible. You can get the perimeter from area very easily. First, you find the square root of the area, which will be the length of each side (assuming it is a square). Then, once you've found the length of each side, you multiply it by 4, and you should have the perimeter.t is not impossible. You can get the perimeter from area very easily.

Maximum area of rectangle with fixed perimeter. The result you need is that for a rectangle with a given perimeter the square has the largest area. So with a perimeter of 28 feet, you can form a square with sides of 7 feet and area of 49 square feet. This follows since given a positive number $A$ with $xy = A$ the sum $x + y$ is smallest when $x = y = \sqrt{A}$. You have $2x + 2y = P \implies x + y = P/2$, and you want to find the maximum of the area, $A = xy$.
